Intensity (physics) - Wikipedia
WEBIn physics, the intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m 2 ), or kg ⋅ s −3 in base units .
Intensity – The Physics Hypertextbook
WEBBy definition, the intensity (I) of any wave is the time-averaged power ( P ) it transfers per area (A) through some region of space. The traditional way to indicate the time-averaged value of a varying quantity is to enclose it in angle brackets ( ).

WEBFeb 20, 2022 · The SI unit for intensity is watts per square meter (W/m2) ( W / m 2). For example, infrared and visible energy from the Sun impinge on Earth at an intensity of 1300W/m2 1300 W / m 2 just above the atmosphere. There are other intensity-related units in use, too. The most common is the decibel.
17.4: Sound Intensity - Physics LibreTexts
WEBSep 13, 2022 · The intensity of the sound wave is the power per unit area, and the power is the force times the velocity, I = \frac {P} {A} = \frac {Fv} {A} = pv. Here, the velocity is the velocity of the oscillations of the medium, and not the velocity of the sound wave.
